 * @extends Ext.DataView
 * &lt;p&gt;Ext.list.ListView is a fast and light-weight implentation of a
 * {@link Ext.grid.GridPanel Grid} like view with the following characteristics:&lt;/p&gt;
 * &lt;div class=&quot;mdetail-params&quot;&gt;&lt;ul&gt;
 * &lt;li&gt;resizable columns&lt;/li&gt;
 * &lt;li&gt;selectable&lt;/li&gt;
 * &lt;li&gt;column widths are initially proportioned by percentage based on the container
 * width and number of columns&lt;/li&gt;
 * &lt;li&gt;uses templates to render the data in any required format&lt;/li&gt;
 * &lt;li&gt;no horizontal scrolling&lt;/li&gt;
